Electricity supply device and electricity reception device
First Claim
1. A power supply apparatus comprising:
- a power supply coil having a ring shape and configured to transmit power to a power receiving coil located externally; and
at least one antenna configured to receive a signal, wherein;
the power supply apparatus transmits the power to the power receiving coil based on the signal received by the at least one antenna,the at least one antenna overlaps a hollow portion of the ring shape of the power supply coil in a central axis direction of the power supply coil which is controlled to transmit the power based on the signal received by the at least one antenna, andat least a part of the at least one antenna is located out of the hollow portion of the ring shape of the power supply coil which is controlled to transmit the power based on the signal received by the at least one antenna.

Abstract
The electricity supply device (100) supplies electricity using electromagnetic force and opposes an external electricity reception coil (153a). An electricity supply coil (102a) has a hollow section (102b), and has a spiral shape. A reader (103) has an antenna disposed in the projected space resulting from projecting the hollow section (102b) in the central axial direction of the electricity supply coil (102a) and at a position more separated from the electricity reception coil (153a) than the opposing surface that opposes the electricity reception coil (153a) and is of the electricity supply coil (102a), and ID data transmitted by an RF tag (154) installed proximally to the electricity reception coil (153a) is received and detected by the antenna. An electricity-supply-side control unit (104) determines the presence/absence of an electricity reception coil (153a) on the basis of the ID data detected by the reader (103).
